Scriptural Commentary
Faith and reason are the two wings on which the human spirit rises to the contemplation of truth. Fideism—faith divorced from reason—is rejected; instead, the following passages ground the chapter’s argument in Scripture.
1. The Mandate for Reasoned Defense
Hahn calls this the foundational apologetics verse. The Greek apologia means a formal, logical defense — not a private feeling, but a public, prepared witness offered with gentleness and respect.
2. The Covenantal Status of Children
For 2,000 years God welcomed newborns into Israel through circumcision. If the New Covenant intended to exclude infants, Scripture would say so explicitly — the Kingdom is a gift of grace, not a reward for emotional maturity.
3. The Authoritative Directive
Baptism is a command, not a preference left to human sentiment. Because Christ possesses all authority, His directives are binding regardless of how “ready” we feel.
4. The Perpetual Promise
The explicit promise to “you and your children” mirrors the Abrahamic covenant. A New Covenant that is greater than the Old surely does not offer less to the next generation.
5. The Intellectual Courage of the Gospel
Dogma is often caricatured by secular culture as superstition. The apologist refuses to be ashamed of it, knowing it is the power of God — and never unreasonable, even where it surpasses reason’s limits.
Synthesis: The Intellectual and Covenantal Case
Three pillars form a reasoned faith: The Command — a response to Christ’s total authority (Matthew 28:18–19); The Continuity — the New Covenant fulfilling the Old (Acts 2:38–39; Matthew 19:14); and The Credibility — a divine mandate to provide a logical defense (1 Peter 3:15; Romans 1:16).
The St. Justin Martyr Principle: “Whatever is true is ours.” Because God is the author of all reality, we do not fear science, philosophy, or logic — we view the best of human thought as seeds of the Word, fragments of truth that find their home in the Gospel.
